Cell layer-specific modification of cell wall is associated with exo-mesocarp split in pistachio (Pistacia vera L.) Pistachio ( Pistacia vera ) is a drought and salinity-tolerant perennial whose fruit features a fleshy exo-mesocarp, or “hull,” that protects the kernel. Hull development and degradation are key to kernel quality, yet the anatomy and mechanisms driving hull breakdown during late-stage development remain largely unknown. Here, we show that the hull contains anatomically distinct layers of hypodermal parenchyma and filler parenchyma. Using a combination of transcriptome analyses and immunohistochemistry, we show that changes in pectin associated gene expression and modification of this polysaccharide are involved in hull cell size increase, loss of cell-cell adhesion, and softening. Anatomical analysis shows that filler parenchyma expands during late-stage hull development while hypodermal parenchyma remains constant in size. Field data suggest that irrigation and humidity affect pistachio hull split, implicating a role for water status in cell expansion. In summary, the complex interplay between molecular, cellular, and environmental changes suggests that cell layer–specific modifications of the cell wall are linked to exo-mesocarp splitting, forming a model for understanding the mechanism of fruit split during ripening in non-berry fruit crops. Highlight Cell-layer specific modifications of the cell wall are associated with cell expansion and loss of cell-cell adhesion, leading to hull split during late-stage pistachio fruit development. ### Competing Interest Statement The authors have declared no competing interest.

Anyway I've a first author pre-print out! doi.org/10.1101/2025... This one is more on the #plantanatomy and #plantdevelopment side of my work, focusing on #fruit cracking in #pistachios. Fingers crossed on the peer review folks.
